Gustav Kahlsch, Rheyt, and Stefan Frst, Gladbach- Rheydt, Germany, assignors to W. Schlafhorst & Co., Gladbach-Rheydt, Germany, a corporation of Germany Applicatin June 1, 1939, Serial No. 276,779

slip oi. It is known that many proposals have been made for equalizing and increasing the thread tension, some of which proposals are lneiective and others very complicated.
The invention applies to a cop winding, machine, in which a cam cylinder serves for imparting the traverse to the thread, according to a prior proposal. The cam groove in the cylinder has a bend in the region of the front reversingpoint, so that the thread travel receives an additional movement and the thread is tensioned. The bend may be a simple one or a multiple one, so that the groove in the region of the front reversing point extends in the form of a serpentine line in such a manner that repeatedtensioning and consequently a vbetter equalization is obtained.
Such bends have already been used on the split drums of quick traverse winding frames, but
it is evident that such splitshapes can only give a diiierent effect because the'thread runs on to the winding in an entirely different manner and the solution proposedyby the invention cannot come into question at all in such frames. 1n these known drums the deflection of the slot merely effects a change in the direction of the `thread. but no change in the thread tension.'
Several embodiments of the invention are illustrated by way of example in the accompanying drawing, in which:
Fig. 1 shows in side elevation a thread guiding cylinder which guides the thread in both directions of traverse,
Fig. 2 is a part partial section of the thread guiding cylinder shown in Fig. 1,
Fig. 3 shows a development ofthe peripheral wall of the cylinder illustrated in Fig. 1,
Fig. 4 shows a' thread guiding cylinder for soealled diagonal feed and f Fig. 5 shows a modified form of construction of the cylinder illustrated in Fig. 1. z
Inall forms of construction the cop I, during its formation, is rotated in the usual manner by the winding spindle 2, whereas the cam cylinder g 3 producing the thread traverse is driven by a separate shaft 4. The ratio of rotation between the shafts 2 and 4 remains constant. The progressive axial feed of the cam cylinder 3 with reference to the-winding spindle 2 isv effected by some means known for this purpose. Y.
`In theconstruction illustrated in Figs. 1 to 3 the cylinder wall 3 has a groove 5 which guides the threadto and fro once at each revolution. Whereas the reversingpoint 6' of the groove 5'at the rear end is normally constructed, it has at the front end a bend -1- which correspondingly iniiuences the thread and increases the thread' tension.
In the form of construction according to Fig. 4
, the thread guide 8 is displaced to one end of the cylinder 3 and the cylinder itself has a groove Iii the return leg of which is interrupted. Therefore the thread f, according to a prior proposal, runs back over the cylinder wall owing to the diagonal feed, until it reaches the pin 9, when it is again caught by the engaging groove I I and again fed forward by the groove I 0. The bend 1 in the region of thefront end of the guiding cylinder 3 acts in exactly the same manner as in theA construction shown in Fig. 1.-
In the form oi construction illustrated in Fig. 5 the groove 5 has a double deection or bend I2 in Ithe region of the reversing point, with the result spindle, a stationary thread guide positioned so' that thread leaving said stationary guide passes bend.
2. In a7 machine for winding conically nosed cops, a winding spindle, a thread guiding cani cylinder rotatably mounted adjacent said winding spind1ea stationary thread guide positioned so v that thread leaving said stationary guide passes part way around said cam cylinder to reach said winding spindle, said cam cylinder having a helical groove closed at the bottom adapted to receive the thread and to guide it to the winding spindle with-a traversing movement, said groove having reversing bends at its* front. and rear limits arid a plurality of additional braking bends near its front reversing bend.
